Argentina’s litigation defense achieved a major breakthrough when the Second Circuit Court of Appeals in New York reversed a USD 16.1 billion judgment against the country and YPF in late March 2026. Burford Capital, which acquired the litigation rights from Petersen Group for approximately USD 16 million, now pursues both a rehearing petition in U.S. courts and threatens international arbitration at ICSID. The government’s legal team under Procurador del Tesoro Sebastián Amerio maintains that neither avenue holds merit, while separate GDP-linked warrant holders have secured favorable rulings in the UK that the IMF wants resolved through good faith negotiations.
